Point group C4h - Dual extruder

thingiverse

In crystallography, a crystallographic point group is a set of symmetry operations, like rotations or reflections, that keep a central point steady while moving other directions and faces of the crystal to the places of features of the same kind. This model uses a dual-extrusion approach. The crystal structure has a tetragonal cell shape. Schoenflies notation: C4h Hermann–Mauguin notation: 4/m Orbifold: 4* OpenSCAD files are included to create custom cells.
